07/02/2016 What is Underground Surveying? Underground surveying embraces the survey operations performed beneath the surface of the earth in connection with tunneling, exploration and construction in subterranean passageways. It is quite different from surveying on the surface. The following peculiarities of underground surveys ...
29/07/2015 Underground mine surveying technology equipment have come a long way in the last few years. In the field of surveying technology equipment used in underground mines, like in many industries, there has been a move away from the use of outdated and often inadequate instruments to state-of-the art equipment. Laser-based mine scanners are a typical example of this trend and are
Gyrotheodlite Gyrotheodlite is a surveying instrument used to orientate an underground survey base line relative to true North. The Instrument is used to find the bearing of any line on the surface or in the underground. Principle of Gyro The gyro attachment consists of a gyro motor suspended vertically, like a plumb bob on a thin metal tape. Its spin axis is therefore held horizontal through ...
Instruments for surveying underground cavities are internal tachymeters, the sectograph, ultrasonic instruments such as the Luch station, and sonar. Dipping compasses are used for surveying boreholes. Among the instruments used for office work are planimeters, pantographs, photocopying devices, drawing tools, calculators, and Drobyshev rules. Precision geodetic instruments (universal ...
Surveying in the mining industry, both in open-pit and underground mines, often goes hand in hand with terrestrial laser scanning (TLS), which is deployed to verify the spatial changes of mining works. Thanks to its high point density and high accuracy, TLS is a very suitable surveying technique for monitoring movements and deformations.

Mining - Mining - Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on
A person who is carrying out a survey at a mine must ensure the survey: uses instruments and equipment of a precision equal to current best industry standards and technology; is to a standard that accords with good engineering practice ; is to an accuracy of not less than 1:5,000. In certain cases, a district inspector may approve (in writing) a survey undertaken by means other than those ...
